How many HTML5 Apps can be served by exactly 1 and the same Service Instance in SAPCF?

[NabiZamani]

Bringing the question here to the community as suggested by gregorw.

We're moving our SAPCP NEO FLP to SAPCF, and that means migrating our UI5 apps. This brings some questions up:

Imagine you have 1000 apps in your SAPCF Central Fiori Launchpad (CFLP, it's the one you get via subscription), and your CFLP + all those apps are in the same sub-account. Each of the apps needs to connect to your 1 backend using the same destination (let's say via HTTP/OData).

Questions:

1. Would you use for each of the apps an own destination service instance (=1000!) or would you share 1 destination service instance for all apps (via mta.yaml)?
2. How about the xsuaa - share 1 service instance or create 1000 service instances?
3. Is there any metric helping to answer how many apps can be served by exactly 1 xyz service instance, i.e. destination service instance, xsuaa service instance, etc...?

I'd like to bring in another good question by jasper_07 (thinking of load balancing, performance etc): Should one setup multiple destinations say by functional area HR/FI/SD for load balancing cloud connector, or somehow by region or other taxonomy?

Any thoughts?

Thanks,
Nabi

Sizing Recommendations (SAP Help):
"Up until now, you cannot perform horizontal scaling directly .. you can distribute the load statically by operating multiple Cloud Connector installations .. multiple destinations with virtually the same configuration"
